This mac had been left overnight multiple times in a row on an old window sill in quite an old house, and in cold weather. This had allowed condensation to build up in the mac, until it killed it. Cleaned up, corrosuion removed, a few caps and resistors replaced solved the most of it, but it still wasn’t powering up as it ought.
Further inspaction took us to the final picture with the large square IC, the big square QFN IC is responsible for power to the Mac. It takes quite the trained eye to see what was not right. Top ‘before’ picture, top right hand corner, can see, barely, but can see the smallest bit of blueish greenish corrosion under the chip. Chip taken off, cleaned up, soldered back on and this Mac is back to being 100% is it ought be, all at a fraction of the cost of Apple.
A less than 1 year old Macbook Pro A1990 dead, no charge light, no anything. Upon opening this up and removal of the logic board, it’s been totalled by water, although the owner said absolutley no way has there been a spill! This was the worst area of a few for this Mac, this is the USB and SSD area, If this isn’t working, there’s no charge, no SSD being seen , oh and no power!
This customer had no backup of their data which was vital. Apple had quoted an obscene amount of money to replace the insides ( never fix) and would 100% loose his data, as that’s what they do. So we fixed this, at a fraction of the cost of Apple by cleaning up the bad areas, and using specialist software we are able to determine the vaues of bad chips, caps, resistors etc, and we can then locate replacements for what’s needed from donor logic boards ( dead ones fro harvesting from ). With all the bad stuff gone and replaced, restored with all of the clients data as it should be.
Macbook Pro A1502 – Mug of peppermint tea killed me!Brought in dead, and dripping with peppermint tea within an hour of the spill. The inital stages of corrosion had already begun, but due getting it to us straight away damage has been minimalised
After cleaning the corroded areas there were only two bad areas that needed work, Power to the CPU has been restored and S0 Rail, which is part of the circuitry that enables the mac to power on.
Upon proof of being an NHS worker shown, a 15% discount was given. Macbook up and running at a fraction fo the cost of Apple, happy customer!
Something less usual, Nintendo Wii U controller very laggy, regardless of resetting, synching and what not. It’s the bluetooth chip failing that causes the issue, bluetooth chip replaced and good to go. Much more is repairable and recyclable then many would imagine..

1TB SSD (Solid state drive) came into us this morning, dead. Like dead dead dead. The machine it came from had been running quite hot. Upon plugging it into any other machine it prevents the machine from booting, and if plugged in via USB caddy to try and see if there’s any data also freezes the machine. A very dead SSD. So we removed it from its housing – Inspected the logic board for any obvious bad areas ( blown resistor or capacitor etc ) , saw nothing, tested with multi meter that circuitry was OK, upon inspecting the two large chips – that’s the actual memory where your data is written to, the solder balls around it looked grey and mushy, as would most very certainly be under neath too. These chips are soldered to the board by an array of sometimes hundreds of solder balls. Knowing it had come from a hot environment we knew it was likley bad solder under thses chips. So, using the correct temperature and pressure reflowed the solder. Look at the before and after pictures, grey solder blobs vs nice shiney solder balls. Cleaned up and plugged into a USB caddy, plugged into our recovery rig and the drive showed up and preseted itself with a corrupt partition table, using specialist tools & software this data is now being recovered to a new drive.
HP Pavilion i7 Nvidia GPU gaming laptop dead from a water spill. As ever gave the caveat to the customer that we generally don’t do PC laptop repairs like this as a) much of the time not worth the cost of the PC, b) we don’t have schematics for PC laptops, not the parts generally speaking. c) the quality of the build of most PC motherboards isn’t upto the violence incurred during ultrsonic cleaning afterwards. Again vital to get data off as a last resort, thankfully not needed. Sacrificed a USB port for replacement caps and resistors and brought this back to life, just minus a USB port – Took half a day ! A small price to pay to get such an awesome laptop up and running again
2017 A1706 Macbook Pro touchbar – Killed by a fruit smoothie. Smells nice though! Mac would start initially and turn off mid boot, 4 USB-C ports not functioning – So no power in nor charge. The right hand pair of USC-C ports were wrecked. cleaned up connector , relaced 2 bad caps and cleaned up the others to restore USB to all ports. Next ( forgot before photo ) below the long connector, to the right we replaced 2 capacitors , 1 of which was hanging off the board – blown clean off. can see the red scorch marks around where it was replaced, that area is resposible for voltage to the CPU. Sorted. next a shorted Hall effect pad which is attached to the SMC, cleared that up, removed the short – Happy SMC. Cleaned up and tested, Keyboard cleaned up, put back together charging correctly and powers on as it should. Back to life at a fraction of the cost that Apple quoted.
A1502 2015 Macbook Pro cider spill. No power, no picture. What did they do to you little Macbook, what did they do? Cider got spilled through the keyboard.Then the worst thing one can do was done. It was placed in a bag of rice and put in the airing cupboard for a few hours, taken out again, plugged in and tried to turn it on again. This caused most of the damage. U5110 area was badly shorted to ground, this area is responsible for SMC reset – SMC is the sytem contoller that when it has all nessecary and correct info and parameters will allow the Mac to turn on. In the state of this, with it shorted to ground leaves the SMC in a state of permanent reset – Which means off! Had to replace a few caps and a resistor and run a wire to U5110 as the trace and pad were wrecked.
Next up, one reason for no picture to screen is the LDVS connection (the cable that goes from graphics output to the screen) being welded to itself and blown pins.Both the LDVS connector on the boards, and the cable from the screen had to be replaced.
Next, we have a very feignt picture now to screen, if we hold a bright light and shine it through the back of the screen through the plastic Apple logo, we can see the feignt flashing image of a folder with a question mark on the screen. Why this folder with question mark? Thats the Mac/ board fired up and booted sayingit cant find the hard drive or SSD to boot from, as we always remove the SSD/ HDD when working on these things to prevend any accidental damage to customer data.- So, the feignt image tells us there is no back light power to screen. The chip that controls this is U7700 – which essentialy take a 12 volt line and whacks it upto 50 volts, that’s what effectivley turns the screen on.
So U7700 replaced along with an iffy looking resistor, and we now have full image to our test screen. Our work is done, keyboard cleaned up, Mac put back together again, and we have one fully functioning Macbook Pro at a fraction of the cost of Apple. 🙌💪✊

Water spill over Macbook Air A1466. As soon as the spill occured, the customer did all the right things. Turned it off right away and unplug it. Leave the lid open , turn the mac upside down and rest it keyboard down on a tea towel. Remove the back (pentalobe driver required ) and disconnect the battery. In this case customer carefully dried it out and cleaned what corrosion had started. Carefully dried it, waited 24 hours and turned it on to find working fine but keyboard doing crazy things. Apple quoted just over £400 with VAT ontop of that to replace the entire topcase – thats the casing, the keyboard, battery, track pad, keyboard backlight, keyboard, DC power in board, to name but a few when its simply the keyboard at fault here. So, we stripped the top case down to the chassis and removed the iffy keyboard and the gazillion tiny screws holding it in (corrosion on cable connector and bad stickey keys and a shorting caps lock !) . Put in the new, screwed back in a gazillion teeny tiny screws, fitted the back light, stuck the battery back in, and put the logic boards etc back into place. Fired up and used keyboardchecker.com to test all keys. All as it should be at a fraction of the cost by Apple to you and the environment. 🙌✊
